ABSTRACT:
A method of detection is described to be used in file system-based player devices to determine the type of compact disk that has been inserted into a player. The method automatically distinguishes between the DTS-CD format and standard audio CDs. The method allows the operating system or CPU software to take appropriate action to decode and playback the audio stream once the a decision between standard audio CD or DTS-CD is made.
